The round cluster is comprised of 19 3.5mm faceted amethyst, one in the center, 6 on the middle layer, and 12 around the base. I also have this cocktail ring available in faceted red garnet, faceted peridot, opal, pearl, cabochon turquoise, cabochon red coral, check my other listings...(All shown in Picture 4) Upon ordering please let me know of your size!
